To neutralize the bitterness of grapefruit tea, you need to add a little more sweetness. Many people who don't like sweetness very much will reduce the amount of cane sugar by half or even less in the process of making it, which will result in the bitter flavor of the yuzu tea being aggravated. One way to synthesize the bitterness well without increasing the amount of cane sugar is to extend the marinating and simmering time in the yuzu tea making process. By simmering it a little longer, the bitter flavor of the pomelo tea will become a little lighter. On the contrary, those who like the bitter flavor can put less cane sugar, add more white pith and shorten the marinating and boiling time.
